Modelling of planar RR manipulator
Bečár, Tomáš ; Chromý, Adam (referee) ; Burian, František (advisor)
This bachelor thesis deals with the model of the manipulator with two arms and servos RX-28 implemented in recent years. Part of the work is to search the kinematics of manipulators, calculate the direct and inverse kinematics task for a given manipulator, determine the accuracy of measuring the position of RX-28 servos and create a PC application to verify the function of the manipulator. The aim of the work is to achieve the accuracy of the pose for the entire handling space.
SMV-2017-03: Planar microstructures for optical applications
Horáček, Miroslav ; Kolařík, Vladimír ; Matějka, Milan ; Krátký, Stanislav ; Chlumská, Jana ; Meluzín, Petr ; Král, Stanislav
Development in the field of planar microstructures for optical applications, physical realization of structures by means of electron beam lithography. The project covers the processing and analysis of the graphical motive, research and application of planar microstructures performing required optical properties, research and modeling of the physical possibilities of implementation of microstructures, regard to the limits of current scientific instruments in our laboratory, data preparation for e-beam lithography exposure, samples exposure, verification of properties of samples and technical documentation preparation.

Večerka, Kamil ; Lukeš, Zbyněk (referee) ; Raida, Zbyněk (advisor)
In this semester work is analyzed broadband planar antennas published in foreign literature, which represents the current trend of planar antennas. It describes the overall design of the antenna including a description and enter your own simulation program Ansoft Designer, comparing simulations for various types of additional resonators and their influence on the resulting frequency characteristics.
Planar Circuits Elements on Low Temperature Cofired Ceramics
Kosina, Petr ; Dřímal, Jiří (referee) ; Kolařík, Vladimír (referee) ; Šandera, Josef (advisor)
The present work deals with the design and manufacturing of 3D structures in LTCC (Low Temperatue Cofired Ceramics) technology. To use this technology LTCC workplaces have been designed and technological processes for high quality reproducible production were suggested. Technological possibilities of low temperature co-fired ceramics were demonstrated in the design and manufacturing of pressure sensors, electrode systems for ozone generators, planar circuit elements (coils and transformers) and in the design a special package for middle-power terahertz modulator. Design of selected parts of respective devices was proved by simulations in COMSOL Multiphysics. The work provides new insights into the structure of power integrated circuits sleeves and structure of electrode systems for different types of electrical discharges. Results of this work can contribute significantly in the application of planar circuit elements, in the development of different types of sensors, in the design of atypical types of packaging or in the design of electrode systems for capacitive coupled electrical discharges.
Design of portal milling machine
Lasák, Štěpán ; Tůma, Jiří (referee) ; Blecha, Petr (advisor)
This bachelor thesis is focused on the field of router type (planar) milling machines. The first part of the thesis presents a brief introduction to the described machine and its main constructional parts. After setting the area of the milling machine’s usage, appropriate parameters will be chosen. Elementary constructional are calculated based on these parameters. At last, a drawing of the assembly and a 3D model of the machine are made.
